Singleplayer Online Mode Rubberbanding, Matbe Cause:Routing Mojang servers

I have been running the game in online mode, but single player, and am having rubberbanding and lag. After extensive conversation with three different AI models (coming to similar conclusions) one potential estimated cause is that "the game has separate "online" and "offline" heroes. If you're playing solo with an online character, your session still routes through Mojang's dedicated servers — even alone."

As the AI seems to estimate, the server check in is a constant thing. If that isn't the case, please do correct me, but I have a suggestion for a potential fix if that were the case

Do server check ins either during loading screens between, or on a timer like 30 seconds or 60 seconds instead of the theorized constant checks. 

Thank you for your consideration, and I look forward to the fix for whatever the true cause of the rubberbanding is even if this isnt it
